[PATCH 11/11] rockchip: google: gru: Migrate to use IO-domain driver

[Jonas Karlman]

Switch to use the IO-domain driver to configure IO-domain based on
device tree instead of a setup_iodomain() function.

Signed-off-by: Jonas Karlman <jonas at kwiboo.se>

This should be runtime tested by someone with a gru device. All DT props
and driver seem to be enabled and I expect the io_vsel and soc_con0 to
be configured with correct value.
